Abstract: 1497892 Transistor logic circuits INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1975 [5 March 1975] 45260/75 Heading H3T [Also in Division H1] An IC logic circuit comprises a semi-conductor layer of one conductivity type including spaced zones of the opposite conductivity type forming lateral transistors T 32 , T 33 , wherein the collector zone of the second lateral transistor T 33  contains further zones of the one conductivity type and serves as the base zone of a vertical transistor T 31  in which said further zones are the output collectors and the semi-conductor layer is the emitter. The output collectors provide logic outputs which are decoupled from each other owing to the high # of the inversely operated vertical transistor T 31 , and the outputs can be D.C. coupled to subsequent logic stages. Further independence of the outputs is ensured in other embodiments by providing Schottky collector contacts, and the switching speed is improved by the use of Schottky diodes, Fig. 9 (not shown). In further embodiments, by including further semi-conductor zones to form further lateral and vertical transistors, complex logic functions such as can be performed in addition to the usual NAND, NOR &c. operations.

Abstract: 1,032,867. Magnetic amplifiers. SUNG CHING LING. Nov. 29, 1962 [Nov. 29, 1961]. No. 46266/62. Heading H3B. [Also in Division G1 A magnetometer comprises a split tube 15 of ferromagnetic material, Fig. 1, a toroidal gating winding 16 which is used to saturate the tube 15 cyclically in the directions indicated by arrows 8 and an output coil 20 in which is induced an alternating voltage with an amplitude proportional to the axial flux H x . The core 15 shown in Fig. 1 may be permalloy or supermalloy and is formed with an insulating magnetic layer 13 in the slit, as shown in Fig. 2a. In an alternative embodiment (Fig. 4, not shown) the toroidal winding is wound over the output coil and the two windings may be screened by a copper foil which is insulated so that it does not form a short-circuited winding. To reduce stray coupling between the two windings two similar magnetometers may be arranged so that their stray fields tend to cancel out. Four magnetometers may form the four arms of a bridge. The capacitor C-1 is used to tune the output winding to twice the gating frequency. Magnetic amplifiers.-The magnetometer may be used as a magnetic amplifier by adding an input coil coaxial with the output coil to produce a magnetic field the current induced in the output winding being indicative of the current in the input winding. Fig. 5 shows a circuit embodying such an amplifier and includes a phase detector to indicate the polarity of the input. Feedback is applied to the amplifier through chokes 1-4 and 1-5. The magnetic amplifier is enclosed in a mu-metal case 50.

Title: Data processing systems
IPC: H03M7/40
Filed: 1972-10-06
Abstract: 1359427 Variable length encoders INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1972 [29 Dec 1971] 46159/72 Heading G4A An input-character (byte) is translated into a minimal redundancy code by sequentially scanning a field of bits representing inner vertices and sinks of a binary tree to generate in a register a path vector to the particular sink corresponding to the input character. In the embodiment described, each input byte to be encoded is assigned a particular value of K from 0 to 5 and corresponds to one of the sinks C, E, F, H, J, K in Fig. 1A. The field representing the tree T=11010010100, where the zeros represent the sinks, is stored in a register. With a 1 initially stored in the right-hand stage of the output shift register P, the bits of field T are scanned sequentially from left to right and P is shifted left (steps 13, 14, 18, 19, 28) until a 0 bit is found (step 14). If K=0 when the first 0 is found this corresponds to sink C and the steps at the left-hand side of Fig. 2 cause shift left of register P until the initial 1 bit is lost and then a final two shifts under control of a counter (step 18) so that the output code 00 is obtained corresponding to the two left-hand branches taken to reach sink C. With higher values of K additional steps 16, 21-23 and 27 are introduced so that path vectors 010 and 011 are generated if the input byte corresponds to sink E and sink F, respectively. If K is still non-zero when sink F is tested, register P is shifted right (step 22) to retrace the path back through inner vertices D (=01) and B (=0) and P is then changed to 1 (step 27) corresponding to vertex G and the tracing process is continued for the right-hand side of the tree until the appropriate sink is reached.

Filed: 1976-11-05
Abstract: 1527939 Electronic stop-watches DAINI SEIKOSHA KK 5 Nov 1976 [11 Nov 1975] 46170/76 Heading G3T An electronic watch provides selective visual display of time of day and elapsed time, and in addition, functions as an interval timer providing periodically, momentary audible indication, e.g. every 5 secs, of elapsed time. In Fig. 1 a frequency divider 1 supplies a 1 Hz signal S1 to a normal timekeeping circuit 2 and (via an AND gate (not shown) controllable by a start/stop signal) to a chronagraph timekeeping circuit 3 each circuit comprising secs, mins and hours counters. A selector circuit 4 enables the contents of either of timekeeping circuits 2, 3 to be displayed on a display device 7. A start signal to the chronograph also initiates the supply of the 1 Hz signal to one of time counters 12, 13, 14 via a respective switch 8, 9, 10 when closed. Timer counters 12, 13, 14 are 5 sec, 10 sec and 15 sec counters respectively. In operation, if for example counter 12 is switched ON, it causes an oscillator circuit 15 to momentarily energize a sound generator 17 via an amplifier 16 every 5 secs. Similarly with counter 13 or 14 switched ON, sound will be emitted every 10 secs or 15 secs respectively. The counter circuits are detailed in Figs. 3, 4 (not shown).

Title: Improvements in and relating to devices for modulating electromagnetic wave energy
IPC: G02F1/1506
Filed: 1961-12-28
Abstract: A device for electrically controlling or modulating electromagnetic wave energy at or near the visible spectrum wave lengths comprises a cell holding electrolyte having a boundary wall, which will allow the passage of said energy therethrough and of which wall an inner surface portion is electrically conductive, electro chemically stable to electrolyte and electrically accessible from outside the cell so that it can receive an electroplated deposit, whereby to inhibit the said passage of said energy, said electrolyte comprising a substance itself adapted chemically to remove the elctroplated deposit. Silver bromide dissolved in a solution of lithium bromide and silver iodide dissolved in a solution <PICT:1002809/C6-C7/1> <PICT:1002809/C6-C7/2> of sodium iodide are referred to as suitable electrolytes.  It is stated that oxygen should be added by aerating the electrolyte. Reference is also made (without giving details) to electrolytes based on sodium, copper and tin.  One construction of device is illustrated in Figs. 9 and 11 where glass or plastic plates 71 and 72 are spaced by a gasket 73 to form a suitable container for electrolyte 70.  The inner faces of the plates carry conductive transparent layers 75 and 76 of a metal oxide, e.g. tin oxide. Connection to the layers is made by wires 78, 80 carried in grooves in the plates.  The conductive layers extend into the grooves as shown in Fig. 12 and are held in contact with the wires by conductive paint 83.  The grooves are closed by synthetic strips 84.  The grooves in plate 71 are staggered in relation to those in plate 72.  A metal film 88 is plated on to layer 75 by charging a capacitor 92 from battery 91 and then discharging the capacitor through the cell by appropriate operation of switches 74. The film is maintained against the self-erasing action of the electrolyte by battery 94 until switches 74 are returned to the left-hand side. Film 88 causes an impinging beam of radiation 86, which normally pases through the device, to be absorbed and/or reflected as shown at 89.  Other constructions are described with reference to Figs. 3-6 (not shown).  In these constructions the control circuit is arranged to provide a reverse current to aid the chemical erasing process.

Title: Pulse correcting circuit
Inventor: PENTO FRANK LOUIS
IPC: H04Q1/45
Filed: 1969-09-25
Abstract: 1286654 Impulse repeating circuits; transistor Circuits WESTERN ELECTRIC CO Inc 25 Sept 1969 [27 Sept 1968] 47160/69 Headings H3T and H4K A pulse corrector comprises the series connection of four timing circuits 108 to 111 with logic circuits 112, 114, and 115, to govern operation of a control relay VG and a pulse repeating relay RG. The pulses are taken off a transmission path over which speech normally passes via resistor R between amplifiers 101 and 102. In the presence of a signal tone of 2600 Hz speech is diverted by way of filter BEF. If the signal is present in sufficient comparative strength a signal guard detector 106 switches it to the timing circuits for pulse correction. Up to a particular signal pulse repetition rate the corrector repeats the pulses with a fixed break interval while for pulses with a faster rate the repeated pulses have a fixed make interval. After a persistence check of 30 ms. applied by operate timer 108 the release timer 109 reproduces the operate timer output with a holdover time of 25 ms. to bridge short signal interruptions. At the onset of operation of the release timer the make timer 110 measures out 42 ms. followed by the break timer 111 which measures out 65 ms. If the repetition rate is so slow that the reactivation of the make timer by the appearance of the next pulse occurs after the expiry of the 65 ms. measured by the break timer, the relay RG is operated for periods of 65 ms. at the received signal pulse repetition rate. If, however, the received pulse rate is fast to the extent that the make timer is reactivated before the break timer has marked the end of its 65 ms period, the relay RG is released earlier so as to be inactive for periods of 42 ms at the received pulse rate. Steady signals are also repeated by relay RG, the make and break timers timing out with RG held from the release timer. With RG operated and VG unoperated (the so-called G-function) the holdover time of the release timer is doubled and this timer receives the signal direct while the discrimination of the guard detector 106 is reduced by disconnection of the input from amplifier 104. A detailed circuit of the pulse corrector is shown in Fig. 2, the received signal being applied to inverter Q16, Q17 and charging C15 over R100 with a time delay of 30 ms before Q18 switches on to switch on Q20 which constitutes the release timer with hold-over time of 25 ms determined by C14 and R96. The hold over time extends to 50 ms if R97 is switched in by RG and VG contacts, this condition occurring when a prolonged signal is received and the received signal is applied direct to Q19 without the delay of C15. Switching on of Q20 triggers Q21 to operate the monostable make timing pair Q22, Q23, with a timing of 42 ms. and which, on relapse, operates the monostable break timing pair Q24, Q25, with a timing of 65 ms. The relay drive circuits Q26, Q27 and Q28, Q29 are governed by the timing circuits according to the logical functions set out in Fig. 1.
